IS230TBAI1CH02 – Analog Input Terminal Board

The IS230TBAI1CH02 is a specialized Analog Input Terminal Board developed by General Electric (GE) for integration into the Mark VIe turbine control system. This board is essential for acquiring accurate analog signals from various field instruments such as pressure transmitters, temperature sensors, level detectors, and other analog monitoring devices.

As part of the GE Mark VIe ecosystem, the IS230TBAI1CH02 provides the crucial interface between field analog signals and the control system’s processing units. It connects directly with I/O packs, such as the IS220PAICH1A or IS220PAICH2A, and routes the signals from field instrumentation for conversion into digital data for processing by the controller. It supports current (4–20 mA) and voltage signals, ensuring flexibility in plant-wide analog input configuration.

The board features multiple input channels (typically 16) and is designed with industrial-grade components that deliver reliable performance even under demanding operating conditions. It is DIN-rail mountable, making it easy to install inside turbine control panels and compact enclosures. The board’s terminal layout is optimized for clear identification, minimizing wiring errors during field installation.

The IS230TBAI1CH02 offers integrated features such as built-in signal conditioning, cold junction compensation (for thermocouple input types), and diagnostic feedback, which allows operators and maintenance engineers to identify faulty channels or wiring issues quickly. In addition, the board is equipped with surge protection and noise suppression mechanisms to ensure signal accuracy and system integrity.

It is widely used in gas and steam turbines as part of the turbine instrumentation and control loop. Applications include temperature monitoring, lube oil system analysis, pressure sensing, and many other field input measurements. The board plays a critical role in ensuring the safe and efficient operation of turbine machinery by enabling real-time monitoring and data collection.

Thanks to its robust design and compatibility with other Mark VIe components, the IS230TBAI1CH02 serves as a reliable and long-lasting solution for analog signal integration in both new and retrofit installations.
